Excellent resistance to atmospheric corrosion of some low alloy high strength steel can lead to the formation of buildings, bridges and other structures designed a new concept , namely the proper selection of these structures exposed high strength low alloy steel components to build . In the case of normal exposure to the atmosphere , exposed to atmospheric corrosion of steel in the first few months of a tight protective oxide film. Sometimes architects chosen bare steel is because they want to get a uniform appearance of atmospheric oxidation of the steel surface , and sometimes it is coated with a protective layer in order to save the economy in order to achieve the purpose . Used in the bare state of these high strength low alloy steel, the design must be considered not long steel surface is wet, but should also pay particular attention to the special atmosphere to ensure that under these conditions the corrosion rate of the steel is allowed. E.g., to enhance learning in conditions of industrial flue gas is obviously undesirable. In order to verify that you can use bare steel under certain circumstances . Atmospheric environment needs to be measured , or even need to be exposed test .
